Oreo the raccoon helped animators capture motions and behaviours for Rocket Raccoon, who is voiced by Bradley Cooper in the Marvel Cinematic Universe's Guardians of the Galaxy franchise. The character, which debuted with James Gunn's 2014 film Guardians of the Galaxy, most recently appeared in Avengers: Infinity War. The character is scheduled for another appearance in the upcoming Avengers: Endgame.

The news of Oreo's death was announced by a Facebook fan page for Guardians of the Galaxy. "Rest in Peace to Oreo the Raccoon, the real-life model for Rocket Raccoon. Oreo was also the Raccoon that went to the red carpet with GotG director James Gunn when the movie debuted in Hollywood. Thank you for your awesomeness, Oreo!" the group wrote.
